Patch #31 : new leagues interface completly unusable: to see scheme of opponent must challenge him, after battle to change team must challenge other opponent or go to seasons.
I think there are still inconveniences.
Bags: 1. Leagues opponents sorting not working at all (see bug reporting)
2. All Mastery's Emblem booster disappearing (see bug reporting)
3. Champion reward - light bulb x0 (i see x2 too, but x0 ! )
Too many bags & inconveniences for one patch. I think it must be rerolled for revision.
